Detailed Description

Representation of the sparsity pattern of a matrix.

Function Documentation

void addnz_sparsepattern	(	psparsepattern	sp,
		uint	row,
		uint	col
	)

Add a non-zero entry to a sparsepattern object, unless it already exists.

Parameters

sp	Target sparsepattern object.
row	Row of the non-zero entry.
col	Column of the non-zero entry.

void clear_sparsepattern

(

psparsepattern

sp

)

Remove all non-zero entries from a sparsepattern object.

Parameters

sp	Object to be cleared.

void del_sparsepattern

(

psparsepattern

sp

)

Delete a sparsepattern object.

Releases the storage corresponding to this object.

Parameters

sp	Object to be deleted.

psparsepattern new_sparsepattern	(	uint	rows,
		uint	cols
	)

Create an empty sparsepattern object.

Parameters

rows	Number of rows of the sparse matrix.
cols	Number of columns of the sparse matrix.

Returns

Empty sparsepattern object.

void print_sparsepattern

(

pcsparsepattern

sp

)

Print a sparsity pattern.

Parameters

sp	Source sparsity pattern.
